YASKAWA SIEPYEULA5001C LA500 Technical Manual 227
Item Specification
Momentary Power
Loss Ride-thru
Stops when power loss is longer than 15 ms and continues operation if power loss is shorter than 2 s (depending on parameter settings).
Note:
• Load size and motor speed can cause the stop time to be shorter.
• Drive capacity will change the continuous operation time. A Momentary Power Loss Recovery Unit is necessary to continue operation through a 2 s
power loss on models 4009 to 4018.
Heatsink Overheat
Protection
Thermistor
Stall Prevention
Stall prevention is available during acceleration, deceleration, and during run.
Ground Fault
Protection
Electronic circuit protection
Note:
This protection detects ground faults during run. The drive will not provide protection when:
• There is a low-resistance ground fault for the motor cable or terminal block
• Energizing the drive when there is a ground fault.
DC Bus Charge LED
Charge LED illuminates when DC bus voltage is more than 50 V.

Temperature Setting
IP20/UL Open Type: -10°C to +50 °C (14 °F to 122 °F)
IP20/UL Type 1: -10 °C to +40 °C (14 °F to 104 °F)
• When you install the drive in an enclosure, use a cooling fan or air conditioner to keep the internal air temperature in the permitted range.
• Do not let the drive freeze.
Humidity
95% RH or less
Do not let condensation form on the drive.
Storage Temperature
-20 °C to +70 °C (-4 °F to +158 °F) (short-term temperature during transportation)
Surrounding Area
Pollution degree 2 or less
Install the drive in an area without:
• Oil mist, corrosive or flammable gas, or dust
• Metal powder, oil, water, or other unwanted materials
• Radioactive materials or flammable materials, including wood
• Harmful gas or fluids
• Salt
• Direct sunlight
Altitude
1000 m (3281 ft) Maximum
Note:
Derate the output current by 1% for each 100 m (328 ft) to install the drive in altitudes between 1000 m to 4000 m (3281 ft to 13123 ft).
It is not necessary to derate the rated voltage in these conditions:
• Installing the drive at 2000 m (6562 ft) or lower
• Installing the drive between 2000 m to 4000 m (6562 ft to 13123 ft) and grounding the neutral point on the power supply.
Contact Yaskawa or your nearest sales representative when not grounding the neutral point.
